Variables | |
msg_hclass_t | sip_request_class [] |
Header class for request line. | |
tag_typedef_t | siptag_request |
Tag for request line object. | |
tag_typedef_t | siptag_request_str |
Tag for string with request line value. | |
#define SIP_REQUEST_INIT | ( | ) |
Initializer for structure sip_request_t.
A static sip_request_t structure for request line must be initialized with the SIP_REQUEST_INIT() macro. For instance,
#define SIPTAG_REQUEST | ( | x | ) |
Tag list item for pointer to a request line structure sip_request_t.
The SIPTAG_REQUEST() macro is used to include a tag item with a pointer to a sip_request_t structure in a tag list.
x | pointer to a sip_request_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_REQUEST_REF().
#define SIPTAG_REQUEST_STR | ( | s | ) |
Tag list item for string with request line value.
The SIPTAG_REQUEST_STR() macro is used to include a tag item with a string containing value of a sip_request_t header in a tag list.
s | pointer to a string containing request line value, or NULL. |
The string in SIPTAG_REQUEST_STR() can be converted to a sip_request_t header structure by giving the string s has second argument to function sip_request_make().
The corresponding tag taking reference parameter is SIPTAG_REQUEST_STR_REF().

Test if header object is instance of sip_request_t.
Check if the header class is an instance of request line object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header request |
0 | (false) otherwise |

Copy a list of request line header structures sip_request_t.
The function sip_request_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.
sip_request_t * sip_request_create | ( | su_home_t * | home, |
sip_method_t | method, | ||
char const * | name, | ||
url_string_t const * | uri, | ||
char const * | version | ||
) |
Create a request line object.
Create a request line object.
Create a request line object with method enum method, method name name, request URI uri, and protocol version version. The memory for the header object is allocated from the memory home home.
home | memory home used to allocate sip_request_t object |
method | method enum |
name | method name (required if method is not well-known) |
uri | request URI |
version | version string (defaults to "SIP/2.0" if NULL) |
|
inline |
Duplicate a list of request line header structures sip_request_t.
Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
|
inline |
Make a request line from formatting result.
Make a new sip_request_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_request_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_request_t.
An sip_request_t structure for request line can be initialized with the sip_request_init() function/macro. For instance,
|
inline |
Make a request line structure sip_request_t.
The function sip_request_make() makes a new sip_request_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |
|
extern |
Header class for request line.
The header class sip_request_class defines how a SIP request line is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_request_t header structure.
